THERMODYNAMIC SUBSTANTIATION OF THE EXPEDIENCY OF REGENERATION OF FLUORINE AND LITHIUM FROM LITHIUM- AND FLUORINE-CONTAINING SALTS. LITHIUM TETRAFLUOROBORATE

Using thermochemical calculations and calculations of thermodynamically equilibrium compositions of substances
in the groups of elements Li–B–F–O–H and Li–B–F–O–H–C, the authors have shown the expediency of regenera-
tion of fluorine and lithium from lithium tetrafluoroborate (component of the electrolyte of lithium-ion batteries) in
its interaction with hydrogen or methane and oxygen in a combustion regime for closing the cycle "production–op-
eration–utilization of lithium-ion batteries" for fluorine and lithium.
